Relationship between mass, slope and velocity.

With air resistance, acceleration approaches zero as time passes. Given adequate time, objects in motion reach terminal velocity, depicted by the flat lines. (a) Objects with different mass reach their terminal velocity over time, given different slope angles. Line colors denote mass and line types denote slope angle. The plot clearly shows that greater mass allows for greater terminal velocity. In this simulation, air density = 1.29 kg/m3, cross sectional area of the object = 1 m3, friction = 0.1 and drag coefficient = 1.05. (b) How different friction forces affect a 1-kg object placed on a 45° inclined slope. Apart from mass of an object, friction also affects terminal velocity. The plot shows a negative correlation between friction and velocity, where larger friction results in decreased terminal velocity and vice versa.
